Polymer pen litho
Using a polymer pen lithography technique, the Air Force Research Laboratory and Northwestern University have developed a quick way to discover new materials.
Researchers have developed a combinatorial library of tiny nanoparticles on a substrate. A combinatorial library, sometimes referred to as a megalibrary, is a collection of different structures. Each structure is enc... » read more

Wireless charging
Engineers at the University of Washington developed a method to safely charge a smartphone wirelessly using a laser, potentially as quickly as a standard USB cable. Safety features of the system include a reflector-based mechanism to shut off the laser and heatsinks.
The charging beam is generated by a laser emitter that the team configured to produce a focused beam in the... » read more

Nanowire batteries
University of California, Irvine researchers invented a nanowire-based battery material that can be recharged hundreds of thousands of times.
Nanowires have long been sought as a battery material. However, these filaments are extremely fragile and don't hold up well to repeated discharging and recharging, or cycling. In a typical lithium-ion battery, they expand and gro... » read more
